* Added more material buttons by William. Thanks.
I made some minor adjustments and added Specular Shader Model RNA.
* Code cleanup and some consistency tweaks of button files.
Notes: Preview render now only shows up when there is an active world, material, texture or lamp.
* Made sure initial panels with ID Datablocks are shown, even when no block is active.
- Changing visible layers for armatures now sends notifiers
- Made the bone buttons show the layers data
TODO:
I also tried making the bone buttons show for 'PoseChannels' instead of the raw bones since this is more correct for most editing that can be done (i.e. when posing). For editmode though, we'd need to wrap EditBones in some way? However, I couldn't seem to get this to work due to the way paths are resolved.
* Added panels with dummy preview template.
* Added constraints panel for bones next to objects, though it
doesn't work that well yet, the operators and code need to be
changed so they don't assume it is one or the other in/out
of posemode.
* Added some graying out in the scene and world buttons.
* Added new modifier tab.
* Fixed problems when no object was selected after delete.
* Added initial Armature, Bone, Curve and Font panels, by William Reynish (Billrey). Thanks!
* Small RNA changes
* Commit revision 20240 and 20268 from trunk. ("Mouse wheel zoom lost after rendering.")
